Hello, Using Buildroot-2012-08, I am building for arm-cortexa9-eabi, crosstools+glibc, kernel base 2.6.38.8 I want to activate hardware floating point support, thus I have unchecked the "Use software floating point by default" My final aim is to use Neon, but the defaut Hardware FPU is fine at this time. The build (from scratch) fails when at glibc: [INFO ] Installing C library headers & start files [EXTRA] Configuring C library [CFG ] configure: loading cache /bigdisk/shared/Buildroot/output.imx6hardfpu/build/build-toolchain/.build/arm-unknown-linux-gnueabi/build/build-libc-startfiles/config.cache [CFG ] checking build system type... i686-build_pc-linux-gnu [CFG ] checking host system type... arm-unknown-linux-gnueabi [CFG ] checking for arm-unknown-linux-gnueabi-gcc... arm-unknown-linux-gnueabi-gcc [ERROR] checking for suffix of object files... configure: error: in `/bigdisk/shared/Buildroot/output.imx6hardfpu/build/build-toolchain/.build/arm-unknown-linux-gnueabi/build/build-libc-startfiles': [ERROR] configure: error: cannot compute suffix of object files: cannot compile The config.log shows: configure:2477: arm-unknown-linux-gnueabi-gcc -c -U_FORTIFY_SOURCE -mlittle-endian -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mhard-float -O2 conftest.c >&5 conftest.c:1: sorry, unimplemented: -mfloat-abi=hard and VFP GCC has not been generated with the harware FPU support. I have attempted several hacks into toolchain/toolchain-crosstool-ng/crosstool-ng.config-glibc ... with no better success Any ideas ?
